When the speed remains constant, the distance travelled is ______ proportional to the time
Solution:
Speed (S) is defined as
S = Distance(D)/Time(T)
If speed is constant, it implies
(1) If D increases T also increases i.e. if distance increases time taken also increases
(2) If D decreases T also decreases i.e. if distance is less time taken is less
Hence we can conclude that distance and time are in direct proportion with each other
D ∝ T
D/T = k
Where k = proportionality constant
✦ Try This: When distance remains constant, the time taken to travel the given distance is ______ proportional to the time.
Speed (S) is defined as
S = Distance(D)/Time(T)
Distance (D) = Time(T) × Speed(S)
If distance is constant, it implies
(1) If S increases T decreases i.e. if speed increases time taken is less.
(2) If S decreases T increases i.e. if speed is less time taken is more
Hence we can conclude that speed and time taken are inversely proportional
ST = k where k = proportionality constant
